Why DTC B1600-15 Matters for Chrysler Owners

If you’re a body shop in Fort Worth TX, a used car dealership, or a salvage vehicle owner trying to get a Chrysler back on the road legally and safely, a trouble code like B1600-15 can be a serious stumbling block. This diagnostic trouble code (DTC) directly impacts your vehicle’s ability to start and run reliably, and it’s especially important if you’re working with a recently replaced engine control module (ECM) or dealing with theft recovery vehicles. Understanding and resolving this code is key to restoring full functionality and passing inspections.

What Does Chrysler DTC B1600-15 Mean?

DTC B1600-15 on a Chrysler translates to: “Engine Anti-Theft Signal – New Engine Control Module Not Configured.”

In simple terms, this means that the vehicle’s anti-theft system is not recognizing the newly installed engine control module. Modern Chryslers use encrypted communication between the ECM and the immobilizer system (commonly part of the SRS or body control module). If the ECM hasn’t been properly programmed or configured, the vehicle will disable the engine start function to prevent unauthorized use.

Common Causes of B1600-15

New or used ECM installed without proper programming
Faulty or incomplete anti-theft key coding
Short to battery or open circuit in the anti-theft wiring
Damaged or missing immobilizer antenna or key fob
Mismatched VIN in modules, common in rebuilt or salvage title vehicles

Collision repair shops and rebuilders should pay close attention when swapping modules, especially if sourcing parts from donor vehicles with different VINs.

Symptoms of B1600-15

Engine cranks but does not start
Security or immobilizer light stays illuminated on the dash
Trouble code B1600-15 stored or active in the scan tool
Communication errors between the ECM and body control module

If you’re a dealership or buyer getting a used Chrysler ready for resale, this issue can delay the sale and complicate the CarFax or AutoCheck history if not handled correctly.
